Parking Lot Drainage Systems for Long Island Commercial Properties

A sinkhole near a drain is a red flag — it typically means the pipe below has failed and soil is migrating into it. This needs immediate attention. Depending on what’s underground around it, we may rehabilitate the pipe with slip lining rather than full excavation. Learn how we diagnose and repair sinkholes in parking lots →.

When a storm drain cover drops below the asphalt surface, water pools around it and the surrounding pavement takes a beating. It’s also a trip hazard and a snowplow magnet. We reset the frame and restore the asphalt collar — one of the most common repairs we do.

A trench drain sitting even slightly high is a target every winter. Repeated hits bend grates, crack frames, and open the drain to water infiltration and freeze-thaw damage. We replace the damaged components and reset the drain to the correct grade.

When a drainage pipe fails near underground electric, gas, or telecom lines, digging out the full run isn’t always practical. Slip lining rehabilitates the pipe through existing access points — minimizing excavation and keeping surrounding infrastructure undisturbed.

Catch basins fill with sediment. Grates corrode. Pipes crack. Most commercial drainage systems need inspection and cleaning well before they show obvious signs of failure. We assess what you have and recommend maintenance or repair before it becomes an emergency.
